A show set in Alaska that frequently features snowy settings and small structures, though S3E10 is titled "Seoul Mates."
Some fan discussions for S3E10 ("shutdown -r") involve metaphors or specific locations like an "ice cream truck" or secluded spots.
While not titled "Ice Shack," it features characters trapped in a building during a climate catastrophe where the earth is moving toward the sun (with a twist ending involving ice).
